Harborough District Council D119550 Appendix D: Flood

HARBOROUGH DISTRICT COUNCIL SFRABROUGHTON ASTLEY1:10,000 DETAILED MAPPINGFLOOD RISK INFORMATIONA small area of Broughton Astley, from Sutton in the Elms south to Arkwright Cottages,is located in EA Flood Zones 2 (medium risk) and 3 (high risk). Further developmentin these areas should be avoided. The remainder of the developed areas arelocated outside the area of flood risk.There are no reports of groundwater flooding in the area.Historical flooding records exist for areas within and around Broughton Astley, withthe majority due to fluvial flooding and overland flow following prolonged heavyrainfall events. Fluvial flooding due to burst river banks of the Broughton Brookis also common in this area.LIMITATIONS OF DATAThe Flood Zone 2 and 3 outlines have medium confidence as they were derivedfrom broad scale modelling techniques. The EA are constantly updating flood zoneinformation. Prior to undertaking sequential testing or allocation of developments,the EA should be consulted to see if more detailed information is available.Any updated flood zone information should be incorporated into the SFRAat the next update and also in site-specific FRAs.SUSTAINABLE DRAINAGE SYSTEMSThe use of Sustainable Drainage Systems (SuDS) is recommended acrossthe whole area. Refer to the main report for more information on sustainable drainageand recommendations (for example, attenuation, combined and infiltration systems)for individual urban areas.FLOOD RISK ASSESSMENT GUIDANCEIn accordance with Planning Policy Statement 25 (PPS25), a risk-based sequentialapproach should be applied at all stages of planning. Flood Zones are the startingpoint of the sequential approach. All planning applications for developmentproposals of 1 hectare or greater in Flood Zone 1 and all proposals for developmentin Flood Zones 2 and 3 should be accompanied by a site-specific Flood RiskAssessment (FRA).As a minimum, site-specific FRAs should identify and assess, in more detail thanthe SFRA, the risks of all forms of flooding to and from the development anddemonstrate how these flood risks will be managed, taking into account climatechange. The FRA should determine the level of vulnerability of the proposeddevelopment (Table D.3, PPS25) and the suitability of the vulnerabilityclassification in the relevant flood zone (Table D.3, PPS25). FRAs should provideevidence to assist in the Sequential Test and, where necessary, the Exception Test.Where sites are located in a Flood Zone with high confidence, modelled floodlevels should be available and this should be used to determine minimumrequirements, such as finished floor levels and access / egress routes.Where sitesare located in a Flood Zone with a medium or low confidence, theFRA may need to define the flood outline at this location.Where modelled information is not available for climate change, or unless otherwiseindicated, the Flood Zone 2 outline has been used as a proxy for the 1 in 100 yearplus climate change flood outline until such a time when more detailed information isavailable.KeyHDC BoundaryLocation OverviewDevelopment LimitsFlood Zone 1 1 in 1000yr Floodplain(includes all areas outsideFZ 2 & 3a/3b)Flood Zone 2 Sewer Flooding Incidents 1000yr Floodplain(as supplied by HDC,Leics F&RS and SevernTrent DG5)Flood Zone 3a 100yr FloodplainAreas that benefit fromFlood DefencesOther RiverCanalReservoirFlood DefencesHistorical FloodingIncidentsFlood Storage AreasGroundwater SourceProtection ZonesDesignated Main RiverFlood Zone 3b Functional FloodplainHistorical FloodingIncidents (as suppliedby Parish Councils)CopyrightSome features of this map are based on information provided by the Environment Agency.

HARBOROUGH DISTRICT COUNCIL SFRAFLECKNEY1:10,000 DETAILED MAPPINGFLOOD RISK INFORMATIONThe majority of the urban area of Fleckney lies outside the EA Flood Risk Zones,although a portion of greenfield land, located towards the north west of Fleckney,lies within Flood Zones 2 (medium risk) and 3 (high risk).There are no reports of groundwater flooding in the area.Historical flooding records exist for areas within and around Fleckney, withsome reports due to fluvial flooding from the River Sence.LIMITATIONS OF DATAThe Flood Zone 2 and 3 outlines have medium confidence as they were derivedfrom broad scale modelling techniques.

HARBOROUGH DISTRICT COUNCIL SFRAKIBWORTH1:10,000 DETAILED MAPPINGFLOOD RISK INFORMATIONKibworth is located within Flood Zone 1 and is considered to be at low risk offluvial flooding.Historical flooding records exist for areas within and around Kibworth.These records suggest that the main cause of flooding in the area is from overlandflow following heavy rainfall events.Kibworth has also been shown to suffer flooding from the River Sence.Historical records show that there have also been incidents of groundwater floodingin this area.LIMITATIONS OF DATAThe Flood Zone 2 and 3 outlines have medium confidence as they were derivedfrom broad scale modelling techniques.
